Abstract (en)
The present invention relates to an intra-aortic dual balloon driving pump catheter device. The intra-aortic dual balloon driving pump comprises: a catheter (2); a first balloon (4) and a second balloon (6) respectively surrounding the catheter, being arranged successively along the longitudinal direction of the catheter (2), wherein the position of the first balloon (4) is placed at the distal end (5) of the catheter (2), and the second balloon (6) is placed immediately adjacent to the proximal end of the first balloon (4); the first balloon (4) and the second balloon (6) are periodically expanded to a dimension that nearly blocks the aortic blood flow and contracted to a dimension that does not prevent the blood flow from passing through; wherein the first balloon (4) periodically inflates in diastole and deflates in systole working as a pump, while the second balloon (6) conversely deflates in systole and inflates in diastole functioning as a valve, altogether leading to blood pumping from contracting ventricle and keeping driving forward ahead in the aorta.
